Schlumberger wireless downhole reservoir testing system

Thursday, March 31, 2011

Schlumberger has launched its EnACT wireless downhole reservoir testing system for land operations, which can be used to optimize reservoir tests by detecting changes in bottomhole conditions and adjusting test designs in real time.

Two-way communication between surface and downhole tools permits the control of downhole tools and the transmission of bottomhole pressure and temperature data to the surface. Data streamed from the reservoir to the surface, combined with the surface data, can be transmitted to a company’s operation center and asset team.

?When reservoir testing, the EnACT wireless system simplifies tool operation for safer downhole testing,? said Devan Raj, marketing and technology manager, Schlumberger Testing Services. ?Clients can now analyze test data during well flow and make better informed decisions while testing.?

The centerpiece of the downhole wireless system is the hub, which contains four independent quartz gauges that provide redundancy and safeguard data capture. The EnACT system has been designed to use the hub with one or more repeaters to extend depth range.

During field testing, the EnACT system proved successful in a variety of conditions in the Middle East and North Africa, says Schlumberger, and direct wireless data transmission was achieved with the hub deployed as deep as 11,200 ft.
